Struck by Swinging Object
When materials are mechanically lifted, they have the potential to swing and strike workers. As the load is lifted, the materials may swing, twist or turn. This movement can catch workers by surprise, and the swinging load could hit them.
Windy conditions are especially hazardous because the load will swing more. Depending on where the worker is standing and the force behind the load, the worker may fall to another level after being struck and sustain even greater injuries. Swinging, loads can also slip from their riggings and strike workers. Loads must be rigged properly to prevent slipage.
When the source of injury has been referred to objects that are not free standing, they are attached at some point or are being held by the worker. This includes instances where a hinge-like motion retracts creating swinging motion in which the worker is struck-by a slamming or swinging motion.
- A worker was working within the swing radius of a barge-mounted crane used in dredging operations. He was hit and killed.
- Two workers were assigned to use a crane to set up on a ground slab at the corner of a building. The 24-piece bundle of rebar was to be picked up and loaded onto the crane's hoist line 50 ft in front of the crane. The operator made the pick-up and was swinging around and lowering it to his left using hand signals when the right pennant line broke at the yoke/bridle. The boom collapsed, striking one of the workers on the head and killing him.
